A claw arcade machine contains stuffed animals and mystery boxes. There are 72 items in the machine. Winning a stuffed animal has twice as many favorable outcomes as winning a mystery box. How many of each item is in the machine?

Answers

50 stuffed animals and 22 mystery boxes.

Step-by-step explanation:

Firstly, we assign variables.

Let the number of stuffed animals be x and the number of mystery boxes is y

The probability of selecting a stuffed animal is x/72 while the probability is selecting a mystery box is y/72

The first one. y2 + 12y - 36
The second one. 16z + 25

The first one would have to be y2-12y-36 in order to be factored in that case your answer would be (y+6)(y-6) and the second answer is (4z+5)

Find the value of x in the figure

Answers

Answer:

x = 100

Step-by-step explanation:

I know that the total is 180 so with that in mind this is what i did to get the answer.

180 - 57 = 123

123 - 23 = 100

Double check your work

100 + 23 = 123

then 123 + 57 = 180

your answer is 100:)

hope this helped!

Answer:

100 because, the bottom line is 180 degrees so do 180-57 which would equal 123 then do 123-23 and there's your answer 100.
